After POR-15
Brief Aside - I was bored the night I did the POR-15 and had some time to kill. I found some car wax in my mother-in-law's garage and decided to give old Betty a wax job. I was pretty amazed at the difference, even if I was technically (and literally) "polishing a turd."
On to the insulation/sound dampening. Nothing new here either, I ended up buying 4 rolls of 4'x10' EZ Cool Insulation. I used 3 rolls for the back, single layers for the sliding door and opposite side wall, and two layers for the bottom, wheel wells, and back cargo area. I didn't really measure things out since this stuff should never be seen once I get the interior back in, I just eyeballed and cut and used scraps wherever I was off. I attached the insulation using 3M general trim adhesive, installation was straight forward. Hopefully I can get the front doors and front floor panel done with the remaining roll, but it will be a while before I get to the front of the bus I think.
As far as costs, 4 rolls of the insulation cost $160 and I spent $40 on the adhesive. By my calculations an equal amount of Dynamat would cost over $600, my unscientific theory is that the Dynamat can't be THAT much better. My other theory is that if it is that much better I probably wouldn't be able to hear my engine running, which is not a good thing.
I took it on a test run after finishing up the back, you can definitely tell a difference already. I think once I get my interior back in and the side panels in place it's going to do what I hoped it would. Here are a few pics...
So now I'm in a holding pattern, waiting for the upholstery guy to hopefully work some magic. I have limited funds so I'm paying him to do the two back seats and the two front seats, I'll have to do the side panels, toolbox, and center console. I might even learn how to sew and try to jazz them up a bit, we'll see. I'm hoping to get the bus back by late July so by football season Betty should be looking good.
